UNITED STATES PATENT OFFICE.

CHRISTOPHER J. GRELLNER, OF ST. LOUIS, MISSOURI.

HAMMER.

SPECIFICATION forming part of Letters Patent No. 241,647, dated May 17, 188 1.

Application filed March 10, 1881.

To all whom it may concern:

Be it known that I, CHRISTOPHER J. GRELL- NER, of St. Louis, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in Hammers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification, and in which- Figure l is a longitudinal section of a hammer embodying my improvement. Fig. 2 is a similar section of the hammer-head detached, and Fig.3 is a detail view, in section, of the upper end of the handle with its holding-plates detached.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to means for fasteninga hammer-head upon its handle; and it consists in the combination, with a peculiarlyrecessed head and notched or slotted handle, of a pair of holding-plates which look the head in place upon its handle, so as to prevent itfrom flying off or working loose, substantially as hereinafter more fully set forth.

In the annexed drawings, A represents the hammer-head, which may be of any desired size and shape, and has an aperture or eye, B, for theinsertion of the handle. This aperture has on opposite sides two steps or shoulders, (Shown at a and 11,) forming an enlarged recess 01 opening, 0, at the top.

0 is the handle, the upper end of which has two notches or incisions, d d.

(No model.)

D and D are the holding-plates, which are bent, as clearly shown in the drawings, to form projections e e at opposite ends and sides. The lower one of these projects into its appropriate notch d in the handle, the upper projection resting in the enlarged recess 0 upon the uppermost shoulder, 12, of the eye or aperture B.

The hammer-head is put upon its handle by first inserting the latter through the eye, then the plates D D are put on the end of handle, after which this is pulled back through the eye until the projections e e are flush with the top of the ham mer-head.

It is obvious that this improvement is also applicable to axes, hatchets, mallets, and all other tools of a like character.

Having thus described my invention, I claim and desire to secure by Letters Patent ot' the United States- 1. A hammer-head the eye B of which is made with shoulders or offsets a bon opposite sides, forming an enlarged aperture, 0, at top, as set forth.

2. The combination of the hammer-head A, having eye B, provided with the offsets a b and enlargement c, handle 0, having notches or in cisions d (l, and holding-plates D D bent to form the projections e e, substantially as and for the purpose herein shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

CHRISTOPHER J 08. GRELLNER.
